When i am trying to book the tatkal ticket, getting the error message : "this site is currently unreachable. Please try after some time". This error is frequent and we can't proceed any more till all the seats are filled, so we end up without booking. I am seeing this from last few days, probable a week. Where as previously this was not the case. There were no such errors and site was very smooth and faster in bookings. Please look into it fix the site error while booking tatkal ticket. Thanks in advance.
